WORKMANS TIME-RECORDER.

SPECIFICATION forming part, of Letters Patent No. 675,325, dated May 28, 1901.

Application filed September 1, 1900. Serial No. 28,792. (No model.)

To all whone it may concern:

Be it known that I, CHARLES E. DELLEN- BARGER, a citizen of the United States, resid ing at Cleveland, in the county of Ouyahoga and State of Ohio, have inventeda certain new and useful Improvement in W'orkmens Time-Recorders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

My invention relates to improvements in the class of workmens time-recording machines which employ as a part of their mechanism hour and minute printing-wheels which are operated by clockwork.

The primary object of the invention is to provide means whereby the hour-wheel will remain stationary with one figure thereon at the impression-point for one hour, but will be compelled at the expiration of each hour to turn instantly the distance between two consecutive figures thereon, and thereby bring the next figure to the impression-point.

Another object of the invention is to incorporate into machines of this class a third wheel bearing characters indicating longer periods of time-as, for example, half-day periods containing as many hours as are indicated by the hour-wheel, (which are indicated as follows, to wit: Monday A. M., Monday P. M., Tuesday A. M., &c.)--and to provide mechanism which will instantly move said wheel the distance between two consecutive characters thereon at the termination of each revolution of the hour-wheel.

The invention consists in'the construction and combination of parts hereinafter described, and pointed out definitely in the claims. p

In the drawings, Figure 1 is a side elevation of so much of a workmans time-recording machine as involves myinvention. Fig. 2 is a sectional view on the line indicated by 2 2 of Fig. 1. Fig. 3 is a plan view of the bevel-gear a, the cam attachments, and the stop and the release arm, which is operated by said cam. Fig. 4 is a rear elevation of the parts shown in Fig. 3. Fig. 5 is a perspective view of the same parts and other parts associated with them. Fig. 6 is a sectional rear view on line 6 of Fig. 1. 4

Referring to the parts by letters, A represents the drivingshaft of the mechanism shown. In a complete machine this shaft is driven through suitable connections by a clock. On its lowerend a bevel-geara is attached, and this bevel-gear meshes with a bevel-gear b, which is fast to a hub B. This hub isloosely mounted on an independentlyrot-atable shaftO.

D, E, and F represent, respectively, the minute-wheel, the hour-wheel, and the halfday wheel, all of which are independently r0; tatable about the same axis. Equally-spaced and consecutively-arranged indicating-figures cl, from 1 to 60, inclusive, project from the periphery of the minute wheel. Equally-spaced and consecutively-arranged indicating-figures from 1 to 12, inclusive, project from the periphery of the hourwheel. Equally-spaced and consecutivelyarranged characters f, indicating successive periods, project from the periphery of the wheel F. A gear d is secured to the minutewheel, and it meshes with a gear I), which is fast to the sleeve B. It is obvious that the continuous rotation of the shaft Aby the clock will produce a continuous rotation of the minute-wheel. H

Rigidly connected with the hour-wheel E is a gear G. The tops of the teeth of this gear are concave, substantially as shown. A disk H is rotatably mounted on the same axis as the shaft 0 and is connected to rotate with said shaft, and its hub h embraces the sleeve.

B. At one point this disk H is cutaway, and tooth h projects radially at this point and is adapted to engage between the teeth g, and thereby to move the gear Gand the attached hour-Wheel E. There are as many teeth in the gear G as there are figures on the hourwheel-viz.,twelvewhere fore the movement of the gear G at a distance equal to the distance between two consecutive teeth causes the hour-wheel to move the distance between two consecutive figures thereon. The shaft A, through its connection with the clock, will make one revolution per hour, which through the described intermediate mechanism will cause the minute-wheel to make one revolution per hour, and the sleeve B will also make one revolution per hour. In this sleeve B is a circumferential slot 17 which extends about ninety degrees. A pin h is driven through a radial hole in the hub h and into the shaft attached to the shaft 0, is brought up to and slightly past the vertical position. This rotation of the shaft and of the diskH transmits no motion to the gear G. As the weighted arm K passes over the center it drops, turning the shaft with it until an arm 0 attached.

to that shaft, comes into contact with a shoulder n on the stop and release arm N. This stopand release arm is pivoted to the frame of the machine, and the bent-over end n of this ar'm engages with a cam P, made fast adj ustably to the shaft A by means of the circumferential slotp and set-screw a Which screws into the gear a. A spring n yieldingly holds said end of the stop and release arm in engagement of this cam. The rotation of the cam, however, slowly pushes back this stop and release arm, and at exactly the expiration of each hour it has pushed it back so far that the arm 0 on shaft 0 is released from the shoulder at on the arm N. Instantly, then,

the weighted arm K falls by gravity, turning the shaft 0 and the disk H with it. During this movement the tooth it engages between two teeth of the gear Grand moves said gear, and consequently the hour-wheel, the exact distance between two said figures on said hour-Wheel. The disk then engages with the concave top of the tooth g and holdsthe hourwheel in this position until at the expiration of another hour these operations are repeated.

The mechanism whereby the wheel F is instantly' advanced one space at the completion of each revolution of the hour-wheel is as follows: A sleeve R is independently mounted in axial line with the shaft 0 on a stub-shaft S. A gear 1", attached to this sleeve, meshes with a gear f, attached to the wheel F, (which gear f, as shown, has twice'as many teeth as the gear 13) Another gear having one-half asniany teeth as there are characters on the wheel F is also attached to the sleeve R. A disk M, which normally engages with the concave face of said teeth, and thereby. prevents any rotary movement of said gear, is

attached to the gear G, At one point this disk is cut away, and along tooth m projects radially at this point and is adapted to engage with the teeth of the gear 0". Once during each complete revolution of the hourwheel'thistooth is brought into' operative re- I claim v p 1.
